Description:

The invention relates to a film packaging bag which has a first side fold and a second side fold which are inserted between a front face and a back face, a top seal seam and at least one longitudinal seal seam, wherein a reclosing device is arranged in the region of the first side fold on the inner side of the bag below the top seal seam and wherein the first gusset forms a reclosable chute when opening a bag section above the recycle means for filling.

A film packaging bag having the described construction is suitable for packaging bulk goods, such as dry food for animals, and has a reclosing device, which allows to dispense the content of the packaging in subsets. In addition to pelleted pet food, suitable packaging goods include, for example, detergents, cat litter, road salt and powdery or granular construction materials. After opening the foil pouch on a bag section above the reclosure, contamination of the contents can be avoided by the reclosure, which also ensures a moisture protection and food and pet food and a certain aroma protection. The removal of the filling material takes place through an opening in the first gusset, wherein the gusset can be pulled out after opening the reclosing device and can be used as a chute. The opening is lockable. The reclosing device can be designed as a so-called zipper closure, which has strip-shaped tongue and groove elements which can be manually connected by pressure and form a latching or circling connection. Also other reclosures,

BESTATIGUNGSEXEMPLAR z. As Velcro closures or reclosures with a self-adhesive strip, are conceivable.

A film packaging bag with the features described at the outset is known from the document WO 2004/092025 A2. It consists of a film folded into a tube. The hose produced by folding has on-side gussets and is closed on the shell side by means of a longitudinal sealing seam and on its upper side by a top-seal seam. Below the top seal, a reclosure is formed on the first gusset formed by a continuous reclosure strip. The W-shaped reclosed strip is located at the first gusset and is not sealed to itself. The reclosure strip is longer than the width of the gusset and secured to the inside of the gusset as well as the adjacent bag surfaces that form the front and back surfaces of the packaging bag. For initial use, a bag section is torn open along a line of weakness above the reclosure located on the inside of the bag. To remove the packaged goods, the first gusset in the region of the reclosure is then unfolded, forming a resealable chute. To reclosure of the foil packaging bag, the upper portion of the first gusset remains in the unfolded state, the reclosure strip then being U-shaped.

From the document DE 203 11 386 111 a film packaging bag with a handle formed from a film strip is known. The film strip is arranged in an upper half of the film packaging bag and connected at both ends to a side wall of the bag. The film packaging bag can also be designed as a gusseted bag with a front surface, a back surface and two side folds, wherein then at the top of the bag a reclosure is provided and wherein the Foil strip near the reclosure at the top of the container is arranged.

The invention has for its object to further develop a film packaging bag with the features described above in such a way that it is easier to handle. In particular, even with heavy and / or large foil bags a precise dosage of individual portions when dumping the contents should be possible.

The object is achieved on the basis of a film packaging bag with the characteristics described above in that a carrying handle is arranged on the second side fold, which is offset in the longitudinal direction of the second side fold centered or eccentric to the bottom of the film packaging bag. Before opening for the first time, the film packaging bag can be transported on the carrying handle in a particularly easy manner. According to the invention, the chute on the one hand and the carrying handle on the other hand are arranged on the opposite side folds of the foil packaging bag. After opening the bag for the first time and folding out the chute formed by the first gusset, the bag held on the carrying handle can easily be tilted with a small amount of effort, whereby a precise portioning of the distributed packaged good is possible even without special skill. Due to the arrangement of the carrying handle along the longitudinal direction of the second side fold, the rest position of the foil packaging bag held on the carrying handle can be varied. If the carrying handle is centrally arranged, for example, in the longitudinal direction of the second side fold, the first side fold and the second side fold run approximately horizontally in a completely filled foil packaging bag in the rest position. With a displacement of the carrying handle to the bag top, the chute is raised with respect to a central arrangement and upon a displacement of the carrying handle in the direction of the bottom of the foil packaging bag, the chute is lowered in the rest position. While with a central arrangement of the carrying handle the film packaging bag can be worn very comfortable, allows an off-center offset to the bottom of the film bag arrangement of the handle in a particularly simple manner complete emptying of the film packaging bag. The carrying handle expediently runs in the longitudinal direction of the second side fold.

In the context of the invention, the front surface, the rear surface and the two side folds can each be provided as a separate film section and joined together to form the film packaging bag. In a preferred embodiment of the invention, however, it is provided that the front surface, the back surface and the side folds are formed by folding an at least two-layered bag film, the bag film on the inside of the bag a layer of a sealable plastic and the outside preferably a layer of a non-sealable Material has. The inner surface of the bag film may for example be formed from a good sealable polyolefin. As a bag film, for example, composite films having an outer surface of polyethylene terephthalate (PET) and an inner surface of polyethylene (PE) are suitable. Between the inner surface and the outer surface further film layers can be arranged without any restrictions to increase the stability and / or the barrier effect. In order to achieve a particularly good barrier effect with respect to various gases, moisture and aromas, for example, a thin metal layer may be provided. Also, composite materials with layers of different polymers can be used in the invention, wherein preferably the polymer composition of the inner surface is designed such that melts at a suitable sealing temperature, only the inner surface. For example, composites of co-extruded polyethylene or multi-layer laminated films of high density polyethylene (HDPE) are suitable. Such films are characterized by a high tensile, tear and dielectric strength. According to the invention, the entire foil bag can be made of polyethylene and therefore easily recycled. The film layer lying on the outer surface is typically printed on its outer or inner side. In the case of an imprint on the inside, the latter is applied before lamination of the outer layer with at least one further, inner layer and is protected against abrasion in the manufactured foil packaging bag by its inner arrangement. When printed on the outside, optionally a thin layer of a protective lacquer may be provided to protect the printed image. Since the reclosing device is arranged on the inside of the bag on the first side fold and the carrying handle on the second side fold, the visual impression and the printed images on the front and rear walls of the packaging bag are not impaired by said handling devices.

For the carrying handle arise in the context of the present invention, various preferred embodiments. In the context of a first preferred embodiment of the carrying handle it is glued as a separate film strip on the outside of the second side fold or, if the outside of the second side fold is heat sealable, sealed. The arrangement of the carrying handle takes place in the context of this embodiment in a particularly simple manner, wherein the tightness of the foil packaging bag in the region of the carrying handle is not limited.

In the context of a second embodiment of the carrying handle, the second gusset has two slots, wherein the carrying handle is formed at least from the edge of the side limited by the slots portion of the gusset and wherein the region of the handle is covered on the inner surface of the bag of at least one Abdeckfolienabschnitt. The section of the side fold forms a handle loop integrated in the outer surface of the film packaging bag, wherein the opening formed on the inside of the bag by the slots is covered by a covering film section. In the context of this embodiment, the grip loop is formed by the second gusset itself, which is why a complicated feeding and precise positioning of a handle bend forming film strip is not required. The gripping loop bordering the slots can be produced in a particularly simple manner by punching, cutting or the like in the production of the film packaging bag. By way of example, the covering film section can be connected to the inner surface of the film by heat sealing, with a sealed sealing seam running around the edge being preferably provided for a tight closure.

The slots may be formed in a particularly easy to implement embodiment of the invention as a straight, parallel lines, but without limitation, for example, to optimize the load, a curved course can be provided. In the context of a preferred further embodiment of the described embodiment of the carrying handle, a reinforcing sheet is fastened to the inside of the bag in the region of the handle loop, wherein the handle loop is formed from the section of the bag foil and the reinforcing sheet bounded at the edge by the slots. By preferably by heat-sealing on the inner surface of the second gusset fixed reinforcing sheet, the load capacity of the handle loop can be increased, so that even heavy foil packaging bags can be transported safely. A particular high load capacity can be achieved if the slots are each arranged between two sealing seams, with which the reinforcing sheet is sealed onto the inner surface of the second side fold. In order to ensure a particularly tight closure, the covering film section preferably completely covers the reinforcing sheet, wherein the reinforcing sheet is surrounded by a circulating, self-contained sealing seam between the covering film section and the inside of the bag.

In the context of a further alternative embodiment, the carrying handle is formed by a separate foil strip, which is fastened directly or via a carrier sheet to the inside of the second side fold and which in use is accessible through an opening in the second side fold, wherein the region of the Carrying handle is covered on the bag inner surface of at least one Abdeckfolienabschnitt.

The film strip may be attached, for example, with its two ends to the inside of the second gusset by gluing or heat sealing, wherein a central handle portion of the film strip is accessible through the opening in the second gusset. In the context of a preferred further embodiment, however, it is provided that the film strip is connected to the inside of the bag via a carrier sheet, which is wider than the film strip, wherein the film strip has a central grip section in the longitudinal direction between two strip ends folded around the carrier sheet and wherein the carrier sheet side of the film strip is directly or indirectly connected to the inside of the bag. In the context of such an embodiment, the film strip is not connected directly but via the carrier sheet with the bag film, wherein the force acting on the carrying handle when carrying the film packaging bag is first distributed to the carrier sheet and thus to a large area laterally of the film strip. Due to the more uniform distribution of force, the load capacity can be significantly increased in comparison to the known embodiments using the same film materials for the bag film and the film strip.

In order to achieve a particularly high carrying capacity of the carrying handle, preferably the folded-over strip end overlap in sections and are connected in the overlapping area, for example by heat sealing, so that the film strip forms a closed loop. The strip ends can optionally also be fixed directly to the carrier sheet by heat sealing or gluing. In the context of the invention is also beyond that the strip ends are not directly connected to each other but only with the carrier sheet. The carrier sheet and the foil strip are covered on the inside of the bag by at least one covering film section. The covering film section is used for sealing the film packaging bag in the region of the carrying handle, wherein at least the kinks of the film strip are covered by a continuous covering film section or by two covering film sections.

In order to be able to grasp the gripping portion on the outside of the bag, the bag film can have cuts or an opening in the form of a cutout extending laterally of the gripping portion in the region of the carrier grip, through which the gripping portion is accessible. Furthermore, a weakening line or perforation may be provided in the region of the carrier grip, wherein the grip section can be released by opening the weakening line of the perforation. The weakening line or perforation is preferably self-contained, so that the film section bounded by the line of weakness or perforation can be completely separated out of the film forming the second side fold. The film section can be connected by heat sealing seams and / or adhesive to the handle portion, wherein the cut-out film section then remains after opening on the handle portion and does not have to be disposed of as a separate part. The second gusset, the foil strip, the carrier sheet and the closure sheet are preferably joined together by heat sealing. In principle, however, a gluing or a combination of gluing and heat sealing is possible. In order to achieve a particularly high load capacity of the carrier strip, this can be formed, for example, from two layers folded together and sealed together.

Before the first opening of the foil packaging bag runs the

Re-occlusion W-shaped at the first gusset and adjacent portions of the front and back surfaces. In order to open the foil packaging bag a first time, the sealing seam in the region of the first fold in such a way be executed that this is easy to separate. However, it is preferably provided that a weakening line is provided above the reclosure, along which an end portion of the film packaging bag can be torn off, so that the reclosure is accessible. For removal of filling material, the reclosable chute formed by the first gusset is folded outwards, which can be closed depending on the design of the reclosing device in the unfolded state. In a preferred embodiment, however, provision is made for the chute formed by the first gusset to be able to be folded back between the front surface and the rear surface in order to enable the reseal, whereby in the case of such an embodiment the reclosing device typically releases the first gusset detachably with the adjacent front surface and the back surface connects. In the context of such an embodiment, the outer edges between the first side surface and the adjacent front or rear surface are preferably formed as folded edges, which are stiffened by longitudinal sealing seams and extending to the top seal. The longitudinal sealing seams serve not only to stiffen the film packaging bag but give in relation to the first gusset the preferred W-shaped arrangement of the reclosing device in the folded state of the first gusset. In order to further reinforce the film wrapping bag and to ensure a good seal even after the initial opening, the reclosing device may be adjacent to a sealing seam which connects the front and back surfaces of the film wrapping bag and extends to the top seam or second gusset. The additional sealing seam limits the resealable chute.

Preferably, a weakening line is provided above the reclosing device, which consists of a combination of an embossing line formed by heat sealing and a laser seam introduced into the outer layer of the composite film and overlying the embossing line. Through the hot the film is deformed under the action of pressure and temperature, and in the laser process a partial removal of material takes place on the outside of the film in the region of the stamping line. The combination of a laser seam with a heat-sealable embossing line results in a line of weakness which is characterized by a very good tear-open behavior. The tearing is smooth and takes place with a defined propagation along the weakening line. Because the laser ablation is limited to the outer layer of the film, the weakening line remains airtight. The permeation of oxygen and hydrogen through the region of the oscillation line is negligible. Where the line of weakness reaches the folded edges reinforced by longitudinal sealing seams, it is expedient to provide notches in the longitudinal sealing seams for crack initiation.

The weakening line can extend parallel to the reclosing device and an adjoining transverse sealing seam which closes the filling material space on the upper side over the entire width of the film bag up to the edges of the second side fold. In the context of the invention, however, it is also the case that the weakening line extends parallel to the reclosing device and then ends with a vertical or inclined section to the top-seal seam.

The reclosing device is preferably formed by a zipper closure and has a film carrier attachable to the bag inner surface of the bag and strip-shaped closure elements integrally formed on the film carrier. The strip-shaped closure elements are manually latched to each other by pressure in the manner of a tongue and groove connection, wherein within the scope of the invention both self-closing reclosure strips or male reclosure strips with at least one projection and associated female reclosure strips with at least one receptacle for the projection can. The film carrier is expediently with two sealing seams, the both sides of the strip-shaped closure elements are arranged, connected to the film packaging bag forming film. In addition to manually latchable reclosing devices, however, other types of reclosing devices, such as, for example, self-adhesive reclosing strips or hook-and-loop fasteners, are also suitable within the scope of the invention.

With regard to the attachment of the reclosing device there are several possibilities. A preferred embodiment of the invention provides that the length of the reclosing device is greater than the width of the first gusset, wherein a central portion of the reclosing device is attached to the inner surface of the gusset and on both sides subsequent end portions of the reclosing device with the inside of the front surface or the back surface of the bag are connected. However, it is also within the scope of the invention that a first reclosing strip is disposed on the inner surface of the first side surface and extends to the outer edges of the bag and cooperates with associated reclosure strips secured to the front surface and the back surface. Suitable profiles for the reclosure strip are described for example in DE 201 15 181 U1.

According to an advantageous embodiment of the invention, all four outer edges of the film bag are stiffened by longitudinal sealing seams. When the film packaging bag is formed by folding a bag film, the longitudinal sealing seam closing the film packaging bag on the shell side can run without restriction along the front or rear surface or into an edge which bounds one of the side folds. In the context of such an embodiment, for example, the longitudinal sealing seam closing the film packaging bag on the shell side can connect the second side fold with the front or back surface of the bag. In the following the invention will be explained with reference to a drawing showing only one embodiment. It show schematically

4 shows a preferred embodiment of the carrying handle in a detailed view,

5 is a perspective view of an alternative preferred embodiment of the handle,

Fig. 6 is a sectional view taken along the line B-B of Fig. 5 with an unopened perforation.

The film packaging bag shown in the figures is formed by folding a bag film and has a front face 1, a rear face 2, an inserted first side fold 3 and an inserted second side fold 4. The film packaging bag is closed by a longitudinal sealing seam 5, a top seal seam 6 and a bottom seam seam, not shown. Affixed to the inner surface of the film packaging bag below the top seal is a reclosure strip 7 releasably connecting the first gusset 3 to the adjacent front face 1 and back face 2 of the bag, the reclosure means being closed prior to the first opening of the foil wrapping bag. For filling material removal a bag section 8 is torn open above the reclosure strip 7 along a weakening line 9 contained in the bag film. Thereafter, the first gusset 3 forms a resealable, fold-out chute. It is clear from a comparative analysis of FIGS. 1 to 3 that the folded edges 10 between the first side fold 3 and the adjacent front or side face 1, 2 are stiffened by longitudinal sealing seams. The longitudinal sealing seams extend from a bottom seam seam, not shown, to the top seam 6 and are interrupted in the region of the reclosing strip 7. The second gusset 4 is limited by outer edges, which are reinforced by longitudinal sealing seams. The cross-sectional illustration in FIG. 3 shows that the longitudinal sealing seam 5 closing the film pouch on the shell side is laid in the second side fold 4 and the second side fold 4 connects with the front or back surface 1, 2 of the pouch. The longitudinal sealing seam 5 fulfills a sealing function, while the sealing seams assigned to the other outer edges only reinforce the folded edges 10 and have no sealing function.

The reclosing strip 7 has a film carrier 11 fastened to the inner surface of the film packaging bag and strip-shaped closure elements 12 formed on the film carrier 11, which form a zipper closure and can be latched to itself by pressure. At the buckling edge 13 of the first side fold 3, the strip-shaped closure elements 12 may be interrupted by a punched or cut. The measure prevents spreading of the gusset area as a result of bending stress the strip-shaped projections of the closure elements 12. In addition to the illustrated continuous self-latching Wiederverschlussstreifen 7 can on the front and back surface 1, 2 on the one hand and the first gusset 3 on the other hand associated with each other Re-closure strip portions are provided which are separated from each other. The length of the reclosure strip 7 is greater than the width of the first gusset 3, wherein a central portion of the reclosure strip 7 is secured to the inner surface of the gusset 3 and adjacent end portions of the reclosure strip 7 with the inner side of the front surface 1 and the Rear surface 2 of the bag are connected.

At the second side fold 4, a carrying handle 14 is arranged, which, as shown in Fig. 2, a slight pouring of contents by a slight tilting allows. The arrangement of the carrying handle 14 along the second gusset 4 is not limited, but this is preferably arranged offset centrally or eccentrically to the bottom 15 of the film packaging bag.

The bag film from which the film packaging bag is made is an at least two-layer composite film which has on the inside of the bag a first layer 16 of a sealable plastic and on the outside of the bag a preferably printed second layer 17 of a non-sealable material. Polyolefins such as, for example, polyethylene, polypropylene, polyethylene copolymer, polypropylene copolymer and mixtures of these polymers are particularly suitable as the polymer for the first layer 16. The second layer 17 is preferably made of polyester, biaxially oriented polypropylene (BOPP) or an oriented polyamide (OPA). The materials mentioned can be printed on the inside and outside. The composite foil may have one or more intermediate layers, e.g. B. a thin metal layer to improve the barrier effect in terms of oxygen permeability, water vapor permeability and the permeability of flavors. In the context of the invention, however, it is also the case that the bag film is formed from polyethylene in several layers, in which case the film packaging bag is particularly easy to dispose of. The weakening line 9 for opening the film packaging bag consists of a combination of an embossing line formed by heat sealing and a laser seam introduced into the outer layer of the composite film and overlapping the embossing line. In the embodiment of FIG. 1, the weakening line 9 extends parallel to the reclosure strip 7 and then runs in a vertical section to the head seam 6 from. The front surface 1 and the back surface 2 of the film bag are connected by a vertical sealing seam 18, which adjoins the ends of the reclosure strip 7 and extends to the top seal seam 6. In the embodiment of Fig. 2, the line of weakness 9 extends parallel to the reclosure strip 7 and an adjoining transverse seam 19 which closes the top of the filling, over the entire width of the film bag to the edges of the second side fold 4. Where the line of weakness 9 the achieved by longitudinal sealing seams reinforced folding edges 10, notches 20 are provided in the longitudinal sealing seams for crack initiation.

In the context of the present invention, different embodiments are possible for the design of the carrying handle 14, which are illustrated by way of example in the figures. Fig. 1 shows a particularly simple embodiment, in which a separate film strip 21 is fixed externally to the second side fold 4 by gluing or in a heat-sealable configuration with the outer surface of the foil packaging bag by heat sealing.

2, a film strip 21 is provided as a carrying handle 14, which is sealed with its ends 22 on the inside of the second side fold 4, wherein a central handle portion 23 of the film strip 21 is accessible through an opening 24 in the second side fold 4 , The region of the carrying handle 14 is covered on the inner surface of the bag by a covering film section 25.

4 shows a detailed view of an alternative embodiment of the carrying handle

14. In the region of the carrying handle 14, a reinforcing sheet 26 is attached to the bag inside, wherein the carrying handle 14 from one edge of two

Slits 27 limited portion of the bag film and the reinforcing sheet 26 is formed. The slots 27 are each arranged between two sealing seams 28a, 28b, with which the reinforcing sheet 26 is sealed onto the inner surface of the bag film. By the longitudinally extending sealing seams 28a, 28b, the bag film and the reinforcing sheet 26 in the region of the carrying handle 14 and in the region which adjoins the opening formed by the handle 14 opening 24, firmly connected, so that a uniform distribution of the load on the Bag film and the reinforcing sheet 26 is reached. The reinforcing sheet 26 is completely covered by a cover film portion 25 on the bag inner side. The cover film section 25 is connected to the inner surface of the second side fold 4 with a circumferential, closed sealing seam 28c which surrounds the reinforcing sheet 26, thereby ensuring a reliable closure of the film packaging bag in the region of the carrying handle 14. In order to prevent the two straight slits 27 from tearing open under load, sealing seams 28d extending substantially transversely to the slits are arranged in the region of the mutually associated ends of the slits 27. The sealing seams 28d each extend from one end of a slot 27 to the associated end of the other slot and have an arcuate shape. By virtue of the fact that the sealing seams 28d extending substantially transversely to the slots 27 are bent in the direction of the carrying handle 14, the load is absorbed mainly in the middle region of the sealing seams 28d, whereby the risk of tearing out of the carrying handle 14 is markedly reduced.

A further alternative embodiment of the carrying handle 14 is shown in FIGS. 5 and 6. The carrying handle 14 has a film strip 21 with a handle portion 23, wherein the handle portion 23 is released by the opening of a weakening line or perforation 29. The limited by the line of weakness or perforation 29 film section 30 of the bag film is connected to the handle portion 23, preferably by heat sealing or gluing. Fig. 6 shows a sectional view along the line BB of Fig. 5, but the perforation 29 or line of weakness is not yet open and so the handle portion 23 is disposed hidden within the second side fold 4 of the foil packaging bag. The film strip 21 is arranged on a carrier sheet 31, wherein end portions 32 of the carrier sheet 31 are folded with strip ends 22 of the film strip 21 to the bag inner side, so that the film strip 21 surrounds the carrier sheet 31 with its on both sides of the handle portion 23 subsequent strip ends 22. The strip ends 22 overlap in sections and, on the one hand, are connected to the end sections 32 of the carrier sheet 31 and, on the other hand, via a layer of the carrier sheet 31 by sealing seams 28e. The film strip 21 forms a closed loop, whereby a very high load of the handle 14 is achieved. The carrier sheet 31 and the film strip 21 are covered on the inside of the bag by a covering film section 25. When carrying the film packaging bag on the carrying handle 14, the weight of the film packaging bag is distributed from the film strip 21 on the carrier sheet 31, wherein the carrier sheet 31 is connected directly or via the Abdeckfolienabschnitt 25 side of the film strip 21 with the bag inside. The load is thereby distributed along the sealing seams 28f extending in the longitudinal direction of the carrying handle 14 and the second side fold 4, so that a tearing out of the carrying handle 14 can be avoided even with large loads.
